The Marvel Cinematic Universe's small-screen sibling, "Agents of S.H.I.E.L.D.," has just tapped into the mythos in a giant way — a Jade Giant way, in fact.

Marvel.com reports that actor Adrian Pasdar, best known for playing high-flying politician and superhero Nathan Petrelli on all four seasons of "Heroes," has been tapped to join the cast of "Agents of S.H.I.E.L.D." in an upcoming episode. Though details of his involvement remain sketchy, Pasdar's character is known: He'll play Glenn Talbot, the mustached jarhead famous in Marvel Comics lore for his vendetta against the Hulk, played in Marvel's "Avengers" movies by Mark Ruffalo.

Pasdar is obviously familiar with the superhero game, thanks to "Heroes," but he has Marvel experience as well; he's voiced Iron Man himself, Tony Stark, in numerous Marvel animated projects over the years.

Now, the tables have turned, and Pasdar is sinking his teeth into a considerably less heroic role — something he's used to thanks to his previous collaborations with Jeph Loeb, the head of Marvel's TV operations, and the man who used to run "Heroes."

"I read the character description and I thought, 'Oh man. Here it is again. The sanctimonious [jerk]. That's what they're coming to me for,'" said Pasdar of his casting. "I said, 'Jeph, are you trying to tell me something?' He said, 'No, not at all! Nobody can play this quite like you, but no.'"

Although it's unclear how Pasdar's Talbott will play into the story of "S.H.I.E.L.D.," his presence leaves one wondering whether or not the Hulk himself might make an appearance on the TV series before the season ends. Why bring in Talbott if Bruce Banner's mean, green alter-ego isn't along for the ride? I believe the correct phrase to use here is, "Stay tuned, true believers."

What do you make of Pasdar joining "S.H.I.E.L.D." as the Hulk-hunting Glenn Talbot?
